Protection Function Description
Relay Latching (86)
Relay can be configured to Latch /Unlatch depending on configuration.
(Latching is possible in presence of Auxiliary supply voltage only)
Reset Delay
This parameter introduces a delay in opening of relay contacts, when the current goes
below the drop out value for current differential. This parameter will not work when manual
reset mode is selected.
Inrush Blocking
Relay is equipped with in-built facility of Inrush blocking to avoid nuisance tripping and
stable operations.
